hwmon: (adt7470) Fix incorrect return code check

2013-08-08T19:43:07+00:00

In adt7470_write_word_data(), which writes two bytes using
i2c_smbus_write_byte_data(), the return codes are incorrectly AND-ed
together when they should be OR-ed together.

The return code of i2c_smbus_write_byte_data() is zero for success.

The upshot is only the first byte was ever written to the hardware.
The 2nd byte was never written out.

I noticed that trying to set the fan speed limits was not working
correctly on my system.  Setting the fan speed limits is the only
code that uses adt7470_write_word_data().  After making the change
the limit settings work and the alarms work also.

hwmon: (max6697) fix MAX6581 ideality

2013-08-03T14:04:50+00:00

Without this patch, the values for ideality (register 0x4b) and ideality
selection mask (register 0x4c) are inverted.

hwmon: delete __cpuinit usage from all hwmon files

2013-07-14T23:36:57+00:00

The __cpuinit type of throwaway sections might have made sense
some time ago when RAM was more constrained, but now the savings
do not offset the cost and complications.  For example, the fix in
commit 5e427ec2d0 ("x86: Fix bit corruption at CPU resume time")
is a good example of the nasty type of bugs that can be created
with improper use of the various __init prefixes.

After a discussion on LKML[1] it was decided that cpuinit should go
the way of devinit and be phased out.  Once all the users are gone,
we can then finally remove the macros themselves from linux/init.h.

This removes all the drivers/hwmon uses of the __cpuinit macros
from all C files.

hwmon: (lm63) Drop redundant safety on cache lifetime

2013-07-08T12:18:24+00:00

time_after (as opposed to time_after_equal) already ensures that the
cache lifetime is at least as much as requested. There is no point in
manually adding another jiffy to that value, and this can confuse the
reader into wrong interpretation.

drivers: avoid parsing names as kthread_run() format strings

2013-07-03T23:07:41+00:00

Calling kthread_run with a single name parameter causes it to be handled
as a format string. Many callers are passing potentially dynamic string
content, so use "%s" in those cases to avoid any potential accidents.
